请告诉我们完整的错误 –

尝试把所有你OR条件在一组括号内的，因此，只有一个结果从他们评估.. – MaggsWeb

它显示无效的文件选择 –

使用此

$allowed = array('zip','rar','docx','ppt');//allowed types 
$filename = $_FILES['file']['name'];//file name 

$ext = pathinfo($filename, PATHINFO_EXTENSION);//extension checking 

if(!in_array($ext,$allowed)) 
{ 
    echo 'Not Valid'; 
} 
else 
{ 
    echo ' Valid' 
}

试试这个代码：

$allowedExts = array('zip','rar','docx','ppt'); 
    $extension = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION); 
    $upload_dir ="uploads/assignments/"; 
    if(isset($_FILES['file']) && $_FILES['file']['name'] !=""){ 
    if ((($_FILES["file"]["type"] == "application/zip") 
     || ($_FILES["file"]["type"] == "application/rar") 
     || ($_FILES["file"]["type"] == "application/docx") 
     || ($_FILES["file"]["type"] == "application/ppt")) 
     && ($_FILES["file"]["size"] < 400000) 
     && in_array ($extension, $allowedExts))

其不能工作 –

用途：

.xls 
application/vnd.ms-excel 

.xlsx 
application/vnd.openxmlformats-officedocument.spreadsheetml.sheet 

.ppt 
application/vnd.ms-powerpoint 
.pptx 
application/vnd.openxmlformats-officedocument.presentationml.presentation 

.docx 
application/vnd.openxmlformats-officedocument.wordprocessingml.document 

.pdf 
application/pdf 

For Zip and RAR 
'zip' => array('application/x-zip', 'application/zip', 'application/x-zip-compressed','application/force-download','application/octet-stream') 


'rar' => array('application/x-rar', 'application/rar','application/x-rar-compressed','application/force-download','application/octet-stream')
